Access Nook Glowlight 4 32gb Storage

Nookie.Reader · 07-10-2024, 09:17 AM

Hi, might be a noob question.
is there any way to access the 32gb storage of the GL4?
ive did a few research but none of them worked.
i was able to find the installing android on nook, but is there any cons in doing that? would it affect my battery? because my nooks battery can only last a few days, not even a week (wifi off and brightness off).
im mostly reading manga so the 5gb sideload is not enough.

if there is a way of accessing it without rooting (im scared of issues. i live in the Philippines, not much support on bricked nooks here)

I hate to even wade into this subject again...

B&N likes that UMS, where you plug in your Nook and it says connected.
What it presents has to be (MS DOS/Windows) FAT-ish because that's the standard.
They give you 5 GB for this area.
You can make this area 20 GB or 1 byte.
B&Ns decision for size was just based on guessing the needs of the customers.
It was not intended to be evil.

There's two ways to proceed from here depending on how you feel.

Keep using the UMS and FAT. Expand the 5,368,709,120 bytes to 20 GB or whatever. You will probably need to be rooted. There is a script for resizing but you'll have to edit this some to get it to do what you want. /system/bin/ums_open_resize.sh

It might be something like this. Backup everything first.

Code:

truncate -s 20G /sdcard/.mass/backingFile.img
fatresize -q -s 20G /sdcard/.mass/backingFile.img
fsck_msdos -y /sdcard/.mass/backingFile.img

The other way is to just keep everything in /sdcard (which is not a physical SD card). The question is if your application can see files there. Then there is how to get files there. You will have to use ADB. The good thing is, you don't even have to be rooted.

FIRST MAKE SURE YOU HAVE NOTHING IMPORTANT SAVED IN THE "NOOK IS CONNECTED" AREA. DOWNLOAD IT TO YOUR DESKTOP. THIS WILL ERASE EVERYTHING THERE.

Code:

C:\>adb shell
$ setprop persist.sys.usb.config adb
$ cd /sdcard/.mass
$ ls -l
-rw-rw---- 1 root sdcard_rw 5368709120 2012-11-02 14:25 backingFile.img
$ echo Hello > backingFile.img
$ ls -l
-rw-rw---- 1 root sdcard_rw 6 2012-11-02 14:46 backingFile.img

So, you just got rid of 5G of wasted space. Keeping a file of some kind prevents it from being recreated without having to disable the scripts.

Code:

$ cd /sdcard
$ mkdir Marvel
^D
C:\>adb push Superman1.epub sdcard/Marvel

Mmm, is Superman DC Comics?

I haven't waded through all the code, but it seems like this 5G is autosizing.
On startup and shutdown it will resize so that there is always some free space on it.
So you can probably add as many files as you want, but you will probably have to reboot if it runs out of space so it can make some more.
